Cereals and grasses are the lynchpins of the Australian Agri-Food industry. Cell walls provide shape, form and barrier properties to the plant and are the basis for both post-harvest mechanical properties and direct nutritional benefits. There is as yet no validated model for the molecular assembly, architecture and mechanical behaviour of cereal/grass cell walls. This project aims to derive such a model, so that predictions can be made concerning the effects of tailoring either plant composition (e.g. at the gene level) or post-harvest treatment in order to achieve desired plant or food properties. The findings will also be relevant to understanding how individual features of cell walls affect digestibility and nutritional properties.

谷物和草是澳大利亚农业食品工业的关键。细胞壁为植物提供形状、形式和屏障性质，并且是收获后机械性质和直接营养益处的基础。目前还没有经过验证的模型的分子组装，建筑和机械行为的谷物/草细胞壁。该项目旨在推导出这样一个模型，以便预测调整植物成分（例如在基因水平上）或收获后处理的影响，以实现所需的植物或食品特性。这些发现还有助于了解细胞壁的个体特征如何影响消化率和营养特性。
